So for me, it's not about being reductionist, but about not anthropomorphizing or using words which which may suggest an inappropriate ethical or moral dimension to interactions with a piece of software.
“Lying” traditionally requires only belief capacity on the receiver’s side, not qualia/subjective experiences. In other words, it makes sense to talk about lying even to p-zombies.
I think it does make sense to attribute some belief capacity to (the entity role-played by) an advanced LLM.
No need to say he "lied" and then use an analogy of him lying to a human being, as did the comment I originally objected to.
